University of New Hampshire junior Olivia Rotondo died over the weekend while attending a music festival in New York. Her death and that of a Plymouth State University student is being blamed on the drug, also known as ecstasy or MDMA.

The Drug Enforcement Administration said there has been an increase in the amount of Molly it is seizing. Special Agent Anthony Pettigrew said the drug is often manufactured in bathtubs, and there's no way users can know for sure what they’re taking.

"They call it the love drug or the hug drug," Pettigrew said.

But Pettigrew said the drug has a dark side. On Saturday, Rotondo became the second person with New Hampshire ties in a week to die after taking the drug, according to investigators.

Pettigrew said Molly is ecstasy.

"Molly is purported to be a purer version of that, and it's generally sold in powder in a capsule," he said.

Because it is supposedly purer, Pettigrew said people tend to think it's safer, and dealers take advantage of that.
